IMPROVEMENT IN ICULTIVATORSV.

Specification forming part of Letters Patent No. 35,1 [8. dated June 2 l, 1862.

To all whom it may concern:

Be it known that I, CHARLES A. UHL, of Millersburg, in the county of Holmes, in the State of Ohio, have invented a new and useful implement or machine for marking furrows for corn-planting and for plowing through and cultivating corn, which I have'entitled Uhls Corn Marker and Cultivator, and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure I is a vertical view; Fig. II, a perspective view, and Fig. III a side view.

The various parts of said machine are lettered in said drawings as follows:

A is the axle-tree, and is constructed of wood, and is eleven feet in length from center to center of spoke or hub.

B represents the wheels, which maybe made of wood and iron, and are about three and onehalf feet in diameter and about three inches in thickness at the rim.

(3 is the tongue, made of wood and the usual length of wagon-tongues.

I) is the seat where the person using the machine may sit.

E E are the plows or shovels, which are made of cast steel, and are from eight to twelve inches in length and about sixinches in width.

F is an iron guide, of two bands of iron adjusted to thebeam above,between which bands the arm of the shovel or plow is held and guided, and is about twelve inches in length.

G is an iron rod connecting the arm of the shovel with the beam above, and is about eighteen inches in length.

H is the iron arm of the shovel or plow, and is fastened to the axle-tree A by means of a hook, as shown in said drawings, and is about three feet in length.

I is a wooden beam, same length as axle-tree and about two inches square.

K K are the iron arms which connect the beam I with the point a, and is about three and one-half feet in length.

L is an iron lever working on a pin, 1), as a center or fulcrum, and is about two feet in length.

M are iron rods connecting the leverM with the beam I, which suspends the shovels E by the rods G, as aforesaid.

c is a beam seven feet in length and about three inches square.

(I is a beam of same length of the axle-tree A, and about three inches square.

0 are beams of wood resting on or fastened to axle-tree Aand connecting and supporting the beams c and d, and are about three and one-half feet in length and four inches square.

fare holes in the iron guide F,in which iron pins are to be placed to regulate the height of the shovel E, and consequently the depth of the furrow.

'Ihose parts of the machine which are intended to be constructed of iron are colored blue in the said drawings, and those parts which are to be of wood are colored yellow.

Theoperation ofthesaidmachinemaybemore fully described as follows: It is intended to be used with two horses, (although it may be constructed to use with one horse when only three plows are attached,) and is of such length of axle-tree that four shovels or plows may be attached, and consequently four furrows made at the same time. While the shovels E are attached to the axle-tree A by the iron arms H, the guides F, through which the arms H pass, will keep the shovels E in line and regulate their direction. When it is desired to lift the shovels E entirely from the earth the operator presses his foot upon the lever L at the point h, and as the foot goes down the pointp .is lifted up, and 19, being connected by rodsM with the beam 1, thebeam I is also lifted up, and the beam I, being connected with the shovel-arms H by the rods G, the shovels are also lifted up. By removing the pressure from the point h the shovels will sink again into the soil, and they may be thus lifted again or permitted to fall at the will of the operator, the depth of the furrow to be regulated by the pins aforesaid placed in the holes f in the guide-bands F.

This machine is thought by me to be useful for the purpose of marking furrows previous to and preparatory to planting, and will secure great regularity of distance between the furrows, and will also be of great use in furrowing through and cultivating corn after the same has commenced growing, it being so constructed that the horses will walk between the rows and the wheels and plows also pass between the rows of corn.

I do not claim the wheels or the operators seat, for such devices have been previonsy the furrows, in combination with the pins inused; but serted in the holesfin the said guide-bands I claim as my invention and desire to secure F, substantially as hereinbefore described and by Letters Patent shown.

1. The arrangement of the lever L, rods m, CHARLES A. UHL. beam Lend plows E, ashereinbefore described, Witnesses: for the purpose of lifting the plows from the J. H. DOWNING, earth, as described. HENRY LEHMAN,

2. The guides F, for regulating the depth of BRYAN GRANT.
